   Is this really a new thing? It feels like they've just crammed a sliver of the same bog-standard parsing we've been doing for decades back into the CFG. I guess that's good for preventing off-by-one-based parsing errors, but

   Minisforum BD790i with 96 gigs of LPDDR5 RAM running Ollama. I run Qwen 110b on the CPU and get around a token per second, which is enough for me to dash off a question and get an answer a few minutes later. Smaller models like CodeLlama th

   My workstation runs a local LLM that allows me to ask deeply technical questions in plain English and receive useful, usually highly accurate (95%+ of the time) responses in a few seconds. It has no memory and requires no Internet access, s

   Google Maps does stroke expansion in WebGL 1 vertex/pixel shaders. The vertex shader converts a linear path-segment "instance" into a quad with correctly beveled/extended endpoints, the pixel shader does some normalizati

   Hi, MurmurHash and SMHasher author here. With the code-golfing obfuscation unwound, Th64 is structured very similarly to MurmurHash. The source data is pre-mixed via "rol(x * r + i, 31)", the hash is mixed via "hash = rol(has

    Some of it I was able to verify immediately, some I confirmed by poking around in Github repos once I knew the magic words, some I haven't verified yet. For example, I wasn't sure if there was good support for USB devices in Rust.

    I don't need an AI to write code for me, but it is _astoundingly_ helpful to have it summarize various design options and new technology stacks without me having to scavenge Google for the obscure corner-cases I care about. I have an i

    Google Maps extends atlases vertically in the rare case that they overflow by creating a new taller texture and blitting the old one into it. Since it's device local it takes almost no time.

    Texture atlases will still be a thing when you're dealing with thousands or tens of thousands of glyphs in a glyph cache (some languages end up with a combinatorial explosion of glyphs due to accent marks and stuff).

    Oh, and we had similar visualizers for atlas usage but they were live views in a popup window rendered via canvas.

    Just wanted to let you know that you converged on the same solution (nested 1d allocators) that I came up with for Google Maps back in 2013ish. We also made heavy use of allocation bitmaps and a few other tricks to ensure that the texture a

    I have one, it's a cute toy but I wish I'd shelled out a few bucks more for the Duo S - better form factor, 8x the ram.

    "CPU modifications are minimal, involving the integration of the PPU interface into the instruction set" This absolutely reeks of bullshit and vaporware. Anyone know what this thing actually does?

    The original SpinRite was a lifesaver back in the days of 100 meg magnetic disks, I paid for a copy and used it to resurrect both my own and my friends' hard drives a few times. It was indeed able to (usually) recover bad sectors that

    I think the Bitboys chip was something different, the game studio I was at at the time did get actual test hardware for the Pyramid3D.

    I remember this chip - flaky drivers but the dev board we got did work. We ended up just using Voodoo something or other, and then the first GeForce boards came out a year or two later.

    Hi, I'm the MurmurHash guy. Neat stuff, and I'm amused that multiply-shift-xor has held up so well for all this time.
